An experiment was developed to simulate inland shrimp farming using diluted seawater (1.9 g L) containing 75 shrimps (Litopenaeus vannamei) per square meter during a growth cycle of 120 days. In this study, the environmental loads of copper and zinc were estimated and compared to anthropogenic sources and shrimp aquacultures in other locations. Both metals resulted primarily from feeding, which accounted for 91.8% of Cu and 97.0% of Zn. Concentrations of Cu (110.8 ± 11.8 μg g) and Zn (69.0 ± 0.7 μg g) measured in the harvested shrimp had higher Cu and lower Zn concentrations compared to those reported for farmed shrimp from Brazil and Mexico. Clearly, organic sludge was the main route of removal for both metals (Cu 46.2%; Zn 92.6%). The annual environmental loads estimated for inland shrimp aquaculture were 598 ± 74 g Cu ha and 5080 ± 328 g Zn ha.
开展了一项实验，以模拟在内陆使用稀释海水（1.9克/升）养殖虾类的过程，每平方米放养75只凡纳滨对虾，养殖周期为120天。在本研究中，估算了铜和锌的环境负荷，并与其他地区的人为来源及对虾养殖的环境负荷进行了比较。这两种金属主要来源于饲料，其中铜的91.8%和锌的97.0%来自饲料。与巴西和墨西哥养殖虾的报告相比，收获的虾中测得的铜浓度（110.8±11.8微克/克）较高，锌浓度（69.0±0.7微克/克）较低。显然，有机污泥是这两种金属的主要去除途径（铜为46.2%；锌为92.6%）。估算的内陆对虾养殖的年环境负荷为每公顷598±74克铜和每公顷5080±328克锌。
